JAKARTA, July 24 (Reuters) - Indonesia, the world's greatest palm oil manufacturer, is evaluating fuel with a view to increasing to 40% from 35% the share of palm-oil mixed into biodiesel next year, the energy ministry stated.

If executed, the B40 mandate might increase biodiesel usage to approximately 16 million kilolitres (KL) next year, the ministry said, from 13 million KL approximated to be consumed in 2024.

"We hope the trials could be completed in December, so that complete application of B40 might be brought out in 2025," energy ministry senior official Eniya Listiani Dewi stated in a statement on Tuesday.

The Indonesian Biofuel Producers Association (APROBI) said the industry had the capacity to satisfy B40 need, with installed capacity anticipated to increase to 20 million KL annually next year from 18 million KL now.

"However we will require more basic materials to meet B40 need," Ernest Gunawan, the secretary general of APROBI told Reuters on Wednesday.

The biodiesel industry would require 13.9 million metric lots of unrefined palm oil to produce 16 million KL biodiesel next year, from the approximated 11 million tons required this year, he included.

Indonesia's most significant palm oil association GAPKI stated a decline in exports suggested there would suffice raw products to provide the B40 required in the meantime.

But the industry would require to evaluate "which one would be better", GAPKI chairman Eddy Martono stated, describing the possibility a boost in exports would make supplying the domestic market less practical.

Indonesia's palm oil output is estimated to reach 54.4 million loads in 2024, a 2.26% increase from last year, while exports are anticipated to decline by 2.47% to 29.5 million heaps as domestic consumption rose, driven by biodiesel required.

The ministry had actually checked the biodiesel, blended with 40% of palm oil, on a train for the first time previously this week, while planning to evaluate the B40 mix on farming machinery, power plants and in the shipping market, it said. (Reporting by and Dewi Kurniawati
